Can I eat it?

In food and water
Never made in amounts you could eat. Laboratories make livermorium one atom at a time. Its longest-lived form lasts about 60 milliseconds. 34

A shell diagram: each ring is an electron shell and each dot is one electron. The nucleus holds 116 protons. The outermost shell is shown in red. Electrons do not travel on rings: they fill orbitals, regions where an electron is likely to be found. The boxes are those orbitals for the electrons outside the Rn core, with one arrow per electron. This configuration is a prediction; it has not been measured.
